Bullying negatively impacts all youth involved—those who are bullied, those who bully others, and those who witness the bullying (bystanders).

Bullying is a type of youth violence defined as any unwanted aggressive behavior by another youth or group of youths who are not siblings or current dating partners; bullying involves an observed or perceived power imbalance and is often repeated multiple times or is highly likely to be repeated. Victims may experience harm or distress from physical (hitting, tripping), verbal (name calling, teasing), or relational/social (spreading rumors, leaving out of group) bullying. Bullying can happen in person and electronically (known as “cyberbullyingexternal icon”), at school or in other settings.

The Facts about Bullying

Bullying can result in physical injury, social and emotional distress, self-harm, and even death. It also increases the risk for depression, anxiety, and poor academic achievement. Youth who bully others are at increased risk for substance use and academic problems.

Bullying is widespread in the United States. Reports from the National Center for Education Statisticspdf iconexternal icon and CDC’s Youth Risk Behavior Surveillance System (YRBSS)pdf icon show:

  • Nearly 14% of public schools report that bullying happens at least once a week.
  • Reports of bullying are highest for middle schools (28%), followed by high schools (16%), combined schools (12%), and primary schools (9%).

Prevention Is Possible

Parents, school staff, and other caring adults can play a role in bullying prevention.

Research on bullying prevention continues to progress, and promising evidence is available for school-wide programs that can prevent bullying by strengthening youths’ relationship and problem-solving skills and modifying physical and social environments for youths’ protection.
